Relationships between philosophical values and conflict management styles
No full textPurposeTo examine the relationships between Boyatzis et al.’s (2000) philosophical value orientations and Rahim’s (1983 & 1995) conflict management styles through an exploratory research study. The philosophical value orientations are identified as pragmatic, intellectual and human. The conflict management styles are represented as integrating, obliging, dominating, avoiding and compromising.Design/methodology/approachThe author collected a sample of 161 participants gathered from Amazon’s mechanical turk digital labor pool. Participants completed a survey measuring their philosophical value orientations, conflict management styles and provided information on demographic characteristics. Statistical analysis was used to explore the relationship between philosophical value orientations, conflict management style scores and demographic characteristics.FindingsThe study demonstrated there were significant associations between the philosophical value orientations and the conflict management styles. Significant associations regarding the philosophical value orientations and conflict management styles were also found across the demographic groups.Research limitations/implicationsThree philosophical value orientations were examined in this study to include pragmatic, intellectual and human; however, there are a multitude of personal and workplace values that could be further studied.Practical implicationsThe practical implications of this study show that employees do bring into the company or organization a set of beliefs and value structures that can influence how they respond and relate to their immediate supervisor in challenging or conflicting situations.Social implicationsThe social implications of this study indicate employees’ behavior and reactions to their immediate supervisor are directly manipulated by the value-based system they have developed prior to joining the organization.Originality/valueNo prior research has examined the relationship between Boyatzis et al.’s (2000) philosophical value orientations of pragmatic, intellectual and human and Rahim’s (1983 & 1995) conflict management styles of integrating, obliging, dominating, avoiding and compromising. This study explores how philosophical value orientations are related to the five conflict management styles manifested within the organizational leader-follower dyadic relationship.</jats:sec

Hijack: Taking control of cots systems for real-time user-level services
No full textThis paper focuses on a technique to empower commercial-off-the-shelf (COTS) systems with an execution environment, and corresponding services, to support realtime and embedded applications. By leveraging COTS systems, we are able to reduce the potentially expensive maintenance and development costs of proprietary solutions. We describe a system called “Hijack ” that enables user-level services to take control of features such as CPU scheduling, interrupt handling and synchronization. In contrast to other approaches that support real-time tasks within the kernel of commodity systems such as Linux, Hijack provides the basis for predictable thread execution at user-level. No changes to the kernel source code are required to support this approach. Instead, Hijack works by using a combination of kernel module support and an interposed execution environment between traditional process address spaces and the kernel. This technique enables system calls and hardware interrupts to be intercepted with bounded latencies via the kernel module, that passes control to a user-level real-time executive. From within the executive, system-wide services and policies can be deployed to over-ride certain features of the underlying kernel, while still leveraging base kernel services where appropriate. Using this technique, we show how a vanilla Linux system can be hijacked to support predictable service execution using a series of user-defined policies. In particular, we show how to deliver and process asynchronous events with bounded latency, using interposition agents within a Hijack execution environment. Results show that for realtime streaming applications, Hijack is able to receive and process packets with significantly lower loss rates and jitter compared to using alternative application-level processes for the same task. ∗ This material is based upon work supported by the National Science Foundation under Grant No. 0615153.

Mutable protection domains: Towards a component-based system for dependable and predictable computing
No full textThe increasing complexity of software poses signicant challenges for real-time and embedded systems beyond those based purely on timeliness. With embedded sys-tems and applications running on everything from mobile phones, PDAs, to automobiles, aircraft and beyond, an emerging challenge is to ensure both the functional and tim-ing correctness of complex software. We argue that static analysis of software is insufcient to verify the safety of all possible control ow interactions. Likewise, a static sys-tem structure upon which software can be isolated in sepa-rate protection domains, thereby dening immutable bound-aries between system and application-level code, is too in-exible to the challenges faced by real-time applications with explicit timing requirements. This paper, therefore, in-vestigates a concept called mutable protection domains that supports the notion of hardware-adaptable isolation boundaries between software components. In this way, a system can be dynamically recongured to maximize soft-ware fault isolation, increasing dependability, while guar-anteeing various tasks are executed according to specic time constraints. Using a series of simulations on multi-dimensional, multiple-choice knapsack problems, we show how various heuristics compare in their ability to rapidly reorganize the fault isolation boundaries of a component-based system, to ensure resource constraints while simulta-neously maximizing isolation benet. Our ssh oneshot algorithm offers a promising approach to address system dynamics, including changing component invocation pat-terns, changing execution times, and mispredictions in iso-lation costs due to factors such as caching.
